“…Instead of a flat display, technologies have been proposed that make an image observable from 360-degrees. Ito et al announced RayModeler [16], which is a cylindrical display with a 360-degree viewing angle. Makiguchi et al [28] investigated a 360-degree interactive tabletop display that can display 3D images on itself.…”

“…Nevertheless, this method only provides an auto-stereoscopic effect within a small space in a particular direction, so the method does not satisfy conditions (1) and (3). Volumetric (volume-swept) displays 8 and recently expanded approaches based on light-field reproduction [9][10][11] are other candidates. Such glasses-free 3D display provides binocular and motion parallax along the circular direction in the horizontal plane: the so-called horizontal-parallax-only (HPO) 3D display.…”

fVisiOn: glasses-free tabletop 3D display to provide virtual 3D media naturally alongside real media

A novel glasses-free tabletop 3D display, named fVisiOn, floats virtual 3D objects on an empty, flat, tabletop surface and enables multiple viewers to observe raised 3D images from any angle at 360 •. Our glasses-free 3D image reproduction method employs a combination of an optical device and an array of projectors and produces continuous horizontal parallax in the direction of a circular path located above the table. The optical device shapes a hollow cone and works as an anisotropic diffuser. The circularly arranged projectors cast numerous rays into the optical device. Each ray represents a particular ray that passes a corresponding point on a virtual object's surface and orients toward a viewing area around the table. At any viewpoint on the ring-shaped viewing area, both eyes collect fractional images from different projectors, and all the viewers around the table can perceive the scene as 3D from their perspectives because the images include binocular disparity. The entire principle is installed beneath the table, so the tabletop area remains clear. No ordinary tabletop activities are disturbed. Many people can naturally share the 3D images displayed together with real objects on the table. In our latest prototype, we employed a handmade optical device and an array of over 100 tiny projectors. This configuration reproduces static and animated 3D scenes for a 130 • viewing area and allows 5-cm-tall virtual characters to play soccer and dance on the table.

“…For the usage of advertising, characteristics that are wide viewing zone and observable by multiple viewers are desirable. Several displays that achieve these characteristics have been constructed [1][2][3]. These displays have wide viewing zone that enables observers to see the image while the observers walk around the display and multiple observers can view it at the same time.…”

360° see-through full-parallax light-field display using Holographic Optical Elements

We propose a see-through cylindrical full-parallax light-field display which is viewable from all around 360 degrees. A rotating cylindrical screen created by the Holographic Optical Elements (HOEs) provides a see-through image that enables multiple observers to view it with the real background scene without using any specific glasses. A high-speed projector is employed to realize this time-division projection system. It is set on the bottom of the display and directed towards a hyperboloid mirror which is placed on the top of the display. The rays projected from the projector is reflected by the hyperboloid mirror and the rays are incident on the rotating HOE surface. Then, as the cylindrical screen rotates, the rays are scanned horizontally and vertically by the HOE screen.Since the HOE has angular and wavelength selectivity, only the rays from the projector is diffracted strongly. Otherwise, the rays from the real scene will not be diffracted by the HOE. Therefore, the proposed display achieves see-through, full-parallax and wide viewing zone. Furthermore, we performed computer simulation to verify the principle.
